Answer:
The building to the left is taller.
Step-by-step explanation:
Building on right:
tan 40° = a/56
a = 56 tan 40° = 46.99
Building on left:
tan 50° = b/49
b = 49 tan 50° = 58.40
The building to the left is taller.

Answer: 15/143. cannot be simplified
Answer:
15/143
Step-by-step explanation:
5/13 * 3/11
(5*3)/(13*11)
which is equal to 15/143
no factor can go in the two numbers at the same time
therefore it can not be simplified

What is the distance between the points (4, -2) and (-1, 10)?
Answer:
d = 13 (distance between two points)
Step-by-step explanation:
(4, -2) and (-1, 10)
(X1, Y1) and (X2, y2)
distance between two points = d = sqrt (X2 - X1)² + (Y2 - Y1)²
d = √ (-1 - 4)² + (10 - (-2))²
d = √25 + 144
d = √169
d = 13 (distance between two points)
George has a part-time job which pays $10 per hour. He has already saved $94 toward the purchase of a new car stereo which
costs $194. If x represents the number of hours he still needs to work in order to buy the stereo, which of the inequalities
symbolizes this situation?
OA $10x + $94 $194
OB. $94x + $ 10 $194
OC $94x + $10 < $194
OD. $10x + $94 s $194
Answer:
[tex]\$10x + \$94\geq\ \$194[/tex]
Step-by-step explanation:
Given
Wage = $10 per hour
Savings = $94
Stereo = $194
Required
Represent the scenario using an inequality
From the question, x represents the number of hours.
If his wage is $10 per hour then, his wage is $10x in x hours
Solving further;
For George to afford the stereo, the sum of his wages and savings must be greater than or equal to the cost of the stereo
Mathematically, this is:
[tex]Wages + Savings \geq\ Stereo[/tex]
Substitute right values for the above expression
[tex]\$10x + \$94\geq\ \$194[/tex]
The options are not well presented, hwever the solution is [tex]\$10x + \$94\geq\ \$194[/tex]
22. Which is the interquartile range for
the city that has the
greater variability
in temperature?
Answer:
40
Step-by-step explanation:
Variability is a measures of the interquartile range of a given set of data. The greater the interquartile range, the more the variability.
The interquartile range (IQR) = Third quartile (Q3) - First Quartile (Q1)
IQR for City A = 70 - 40 = 30
IQR for City B = 80 - 40 = 40.
City B has a greater IQR value, therefore, it has the greater variability in temperature.
The interquartile range for the city with greater variability is 40.
If f(x) = -6x - 3, find f(x) = 21.
Answer:
[tex]\huge \boxed{x=-4}[/tex]
Step-by-step explanation:
[tex]\sf f(x)=-6x-3 \\\\\\ f(x)=21[/tex]
Applying substitution method and solving for the value of x.
[tex]\sf 21=-6x-3[/tex]
Adding 3 to both sides.
[tex]\sf 24=-6x[/tex]
Dividing both sides by -6.
[tex]\sf -4=x[/tex]
[tex]\huge\underline\bold\blue{ƛƝƧƜЄƦ}[/tex]
[tex]\large\boxed{f(x)=-129}[/tex]
Step-by-step explanation:
Given - f(x) = 21
Now we have to put the value in the given equation
f(x) = -6x-3
f(21) = -6(21) -3
= - 126 -3
= -129

When |x−y| = 0, what best describes the possible values of x and y?
Answer:
x must equal y
Step-by-step explanation:
|x−y| = 0
For this to be true
x-y = 0
That means x-y+y = 0+y
x=y
Amir wants to do a full painting on the surface of a pottery. The pottery is in the shape of a cylinder with a height of 14 cm and a radius of 4.5 cm. If one tube of colour can be used to paint 120 cm² of drawing, calculate the number of tubes of colour needed to paint 15 potteries of the same type.
Answer:
About 66 tubes
Step-by-step explanation:
Cylinder surface area formula: 2πr(h + r) where h = height and r = radius
In this case, h = 14, π = 3.14 and r = 4.5 so the surface area of one pottery is:
2 * π * 4.5 * (14 + 4.5) = 166.5π ≈ 523.08
The surface area of 15 potteries would be 523.08 * 15 = 7846.2 so it would take 7846.2 / 120 = 65.385 ≈ 66 tubes. We round to the nearest integer because in this context, you can only have integer values of tubes, you can't have, say, 0.5 tubes.

Ben's average speed will be equal to 70.5 meters per minute.
What is an average speed?Calculating average speed involves dividing the whole distance travelled by the total time it took to cover that distance. Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
It is given that Ben walks 500 meters from his house to the corner store. He then walks back toward his house but continues 200 meters past his house to talk to a neighbour. It takes Ben 17 minutes from the time he leaves his house until he stops to talk to his neighbour.
The average speed is calculated as below:-
Average speed = Total distance / Total time
Average speed = ( 500 + 500 + 200 ) / 17
Average speed = ( 1200 ) / 17
Average speed = 70.5 meters per minute.
Therefore, Ben's average speed will be equal to 70.5 meters per minute.

27 piece of steel is cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 1 inch more than five times the length of the first piece. find the length of pieces
Answer:
where x is the length of the first place
[tex]x+1x+5x+1=27[/tex]
[tex]x=\frac{26}{7}[/tex]
Answer:
first piece: 3.25 inches
second piece: 6.5 inches
third piece: 17.25 inches
Step-by-step explanation:
a + b + c = 27
b = 2a
c = 5a + 1
a = first piece length
b = second piece length
c = third piece length
then:
a + 2a + (5a+1) = 27
8a + 1 = 27
8a = 27-1
8a = 26
a = 26/8
a = 3.25 in
b = 2a
b = 2*3.25
b = 6.5 in
c = 5a+1
c = 5*3.25 + 1
c = 16.25 + 1
c = 17.25 in
Check:
3.25 + 6.5 + 17.25 = 27

Phalicia is a senior at North HS and wants to begin saving for college. She's trying to choose between two savings account options.
Option 1: Phalicia deposits $300 and deposits an additional $50 each month.
Option 2: Phalicia deposits $5 and it triples each month.
Which option should she choose
Answer:
Option 2
Step-by-step explanation:
Let's say that Phalicia opens her savings account one year (12 months) before she goes to college.
With Option 1, she would have saved 300 + 50 * 11 = $850. We do 50 * 11 and not 50 * 12 because she deposits $50 for 11 months, not 12.
With Option 2, she would have saved 5 * 3¹¹ = $885735. Note that we do 3¹¹ and not 3¹² because 5 is being tripled 11 times.
Obviously, she should choose Option 2 because she saves A LOT more money.
Additionally, we can notice that Option 1 is an example of an arithmetic sequence whereas Option 2 is an example of a geometric sequence. Their explicit formulas would be aₙ = 50n + 250 and aₙ = 5 * 3⁽ⁿ⁻¹⁾ respectively.

Use the number line to determine the absolute value. Enter the value, as a mixed number in simplest form, in the box. ∣∣−2 2/3∣∣ = Pleasee help will gove brainliest!
Answer: 2/23
Step-by-step explanation: Absolute value is a term which is used to indicate the distance of a point or number from the origin of a number line or coordinate system.
Suppose x is a real number. Then the absolute value of x is defined as follows:
For x = 0 or x > 0, | x | = x
For x < 0, | x | = - x
Now, we have to find the absolute value of the given number that means we have to find the distance of from the origin of a number line.
Distance of from the origin is . As distance can never be negative.
Therefore, the absolute value of is 2/23 .
